C-4 CARESCAPE V100 Vital Signs Monitor 2048723-002C
Electromagnetic compatibility (EMC): Electromagnetic compatibility (EMC): CARESCAPE V100 monitor
Guidance and manufacturer’s declaration – electromagnetic immunity
The CARESCAPE V100 vital signs monitor is intended for use in the
electromagnetic environment specified below. It is the responsibility of the
customer or user to assure that the CARESCAPE V100 vital signs monitor is used
in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications equipment
should not be used closer to any part of the
equipment, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
Conducted RF
IEC 61000-4-6 3 Vrms
150 KHz to 80 MHz
3 V rms
d = 1.2
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz to 2.5 GHz
3 V/m
d = 1.2 80 MHz to 800 MHz
d = 2.33 800 MHz to 2.5 GHz
where
P
is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer, and
d is the recommended separation
distance in meters (m).

Interference may occur in the vicinity of equipment
marked with the following symbol:
Note 1 : At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected by reflection from
structures, objects, and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the equipment is used
exceeds the applicable RF compliance level above, the equipment should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the equipment.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
